Printing supplies application and purchase

The large-format printer is a professional-grade print output device, which is mainly used for inkjet, CAD, GIS, and other specific large-format color printing environments. As a professional fine output device, its use of consumables is particularly strict. In the current printing consumables market, all kinds of counterfeit consumables are flooded with them. Purchasing these counterfeit products or excessively using filling consumables not only causes damage to the printer, but also seriously affects the print quality. Users can only use and purchase large-format printing consumables in order to use the large format printer as an efficient weapon. The print quality of large-format printers is related to many factors such as the environment, temperature, humidity, media, and ink supply system. In the process of using large-format printers, users should pay attention to the following issues and master the skills of purchasing supplies.
First, prevent "leakage". Leaking ink is the enemy of printing. How does it leak out?
(1) Some users use filling inks to mask the intelligent chips of the machine's ink supply system so that they cannot monitor the use of ink effectively. The information fed back by the chip is incomplete and cannot effectively guide the user to use ink to generate ink leakage.
(b) There is always some air inside the cartridge, and the air pressure remains normal due to the presence of air holes. Too much ink is filled into the ink cartridge by the ink filling method, which destroys the pressure in the printer head and the airtightness of the ink cartridge, causes the pressure adjustment function to malfunction, the temperature in the ink cartridge rises, and the internal pressure is greater than the external atmospheric pressure, and the ink is printed from Sprayed out of the head, causing ink leakage.
(3) The chemical composition of the filled ink does not meet the technical standards. After being left for a period of time, it easily deteriorates, producing large and small particles, which not only corrodes the print head, but also causes the nozzles to clog and not to print. When the machine vibrates strongly, ink leakage occurs.
(4) When ink is filled into the ink cartridge, the sticker at the ink hole does not adhere to the lid, or the action of installing the ink cartridge is "rough", and the force is too great to destroy the size of the air hole and change the size of the air hole. When the speed of the machine is increased, the ink is ejected from the nozzle, causing ink leakage. It can be seen that more than 90% of “ink leakage” is caused by using filling ink. The use of filling ink not only causes serious damage to the ink supply system, print heads, and machine equipment, but also the small color gamut of the filled ink, which makes many colors impossible to express, is prone to color shifts, causes color differences, is not realistic, and prints images. Poor quality. Original ink will not produce ink leakage.
Second, anti-static: static electricity is a relatively static charge, is the friction between different objects generated on the surface of the positive and negative charge. Large-format printers are sophisticated mechanical devices and sophisticated electronic products that embody modern technologies. They are also one of the machines that are prone to static electricity. The generation of static electricity not only damages the print quality and the printer, but also has an impact on human health. How is static electricity generated? In the case of large-format printers, the area of ​​contact between the central axis of the machine and the paper is relatively large. If a compatible medium is used, since the surface of the machine is not covered by a special coating layer of the original medium, the electrical conductivity is not strong and it is easy to contact and rub it. Generate static electricity. To prevent the generation of large-format printer static electricity, it is necessary to use original consumables. All of HP's original media surfaces are coated with special antistatic coatings. Original HP media has undergone rigorous electrostatic testing to ensure safe and secure use on the device. Informal manufacturers of media products, because the surface of the original coating without a special layer of the media, the quality is difficult to guarantee, it is easy to produce static electricity when printing.
Third, pay attention to environmental protection: Environmental protection is an important aspect of the use of consumables. Using filling ink, it is easy to cause pollution to the environment. This is not the case for original consumables. Taking HP supplies as an example, HP ink passed the German “Blue Angel” environmental certification during the design and production phase. HP's requirements for ink are very strict. It is non-toxic and harmless. It does not pollute the environment. The packing boxes, promotional materials, instructions, packaging plastics and foams used in HP supplies are all biodegradable and recyclable materials. The formula for filling ink is very imperfect and its composition poses a greater threat to the environment. In the installation and use phase, the ink cartridges of the HP large-format printer are independent, and the installation is particularly convenient. After the ink is used up, it can be replaced separately, which is simple and convenient and does not pollute the environment. With the use of filling ink, the ink is easily spilled, causing the floor to be garish, which not only undermines the beauty of the working environment, but also is troublesome during installation. During the recycling phase, Hewlett-Packard reclaims the original ink cartridges for free, and the waste ink cartridges do not pollute the environment. Many filling companies, after recycling the original empty ink cartridges, directly fill in the inferior ink, and then use the original ink to sell them, in order to pretend to be true, shoddy, and deceive consumers, and seek profits. This is the biggest pollution to the market environment.
Fourth, to save printing costs: In the process of using large-format printers, some users in order to immediate interests, whether it is ink or paper, all compatible or filling consumables. In this way, the cost is increased. Large-format printers are large-format color printers, and the consumption of consumables is astonishing. Due to the different quality and performance of different consumables, there is a big difference in the user's later application costs. Original consumables have excellent print quality and will not cause damage to the machine. Compatible consumables are cheaper, but the print quality will be affected, and even the machine will be damaged. The cost for later maintenance is higher. According to the Gartner report of the well-known IT system project verification and decision authority, the use of original ink with high reliability and high print quality can reduce labor costs and other costs, while the use of filling ink not only affects print quality, but also reduces reliability. And the low output rate, the need to replace the ink cartridges often, increase the purchase cost, so that the labor costs rise, offset the original price difference with the ink cartridge. When users use consumables, they must fully consider the printer's requirements for print media, and comprehensively consider factors such as printing cost. Not only depends on the purchase cost of consumables, but also depends on the maintenance cost of the machine and the opportunity cost caused by the damage to the machine. It is only reasonable considering the overall cost.
Fifth, the right choice of supplies: combined with the application of large format printers, in the purchase of supplies, we must put the original supplies into the first place, to prevent the purchase of counterfeit supplies products. This requires mastering methods to identify genuine and consumable supplies:
1, see the price difference: fake real goods prices greatly.
2, try to find HP designated supplies agents to buy ink cartridges: To avoid buying fakes, the easiest way is to HP throughout the country's "original supplies assured stores" to buy.
3, with the actual situation to buy the method. In the purchase of HP original ink, must be combined with the actual use of the color image output, or text output, to select the ink cartridges of different sizes.
4, comprehensive consideration of the manufacturer's service situation: For example, such powerful manufacturers as HP, its technical support and after-sales service is strong, buy their products will have a higher sense of security.
Comprehensive use of large-format printing supplies and purchase conditions, we can see, in order to ensure print quality and machine is not damaged, the most important thing is to use original supplies, and HP large format original supplies are compatible with its large format printers, regardless of Technology or performance is even better. Therefore, the use of HP's large format original consumables is the user's first choice; only purchasing HP original large format consumables is the shortest way to save overall printing costs.
